I don’t have a complete answer but I’ll help u some. Building dams and rerouting rivers are two examples of ways humans directly impact water in watersheds. Humans also use water as a resource, drawing from watersheds for our drinking water. This does not have to be a negative impact, as water usage can be monitored so that it is sustainable. Hope this helped. ;)

the correct answer is: " ventricles " .

"recent advances in brain imaging have allowed clinicians to make scientifically useful comparisons in the relative size of the chambers in the brain that are filled with cerebrospinal fluid."

{source: refer to text within question.}.

these chambers are called ventricles .
